Not that this is helping me with the interchange issues !!!!
Cahin was fine and complete, it was a near new chain, an original steel Yamaha one , they are bullit proof.
The chain derailled and came off the back sproket and keep feeding through. IT was more bad luck and a few condition that took it to where it was.
The track had been in a shitful condition all day ( race one im sure i seen a rabbit pop out of one of the holes) so the rear was up and down all day i had noticed the chain getting some slack early and re tightened it so i know it wasnt a stretch, from what i can see as the bike came off the corner through the bumpy shit under full load the wheel loaded and unloaded the snail had worked its way around enough to let the whell move that 5mm and gave enough slack so it popped off in a condination of lean angle, slack in the ride postion in suspention unloading and general bumpy conditions.
i had fitted this complete wheel cause i was testing a tyre pattern, but i noticed later that wheel used a differant snail cam, but it had no detents in it, unlike the one the other wheel uses. I think the torque had pulled the wheel forward during the races and caused the cam to slip enough as it had no stop to resist. Small oversight but a big cost.
Davey i had only just taken off the Trick cover and fitted a DT1 cut down case Thank Fuc.... i see someone has one listed on ebay for buy now $499, so i think with a bend rod as the only real YZ part casuality, seeming got out of this one lightly, the Dirt track gods where smiling for once
